EZBook 3 Pro BIOS unlock

[TheGiolly]

Hello guys, I'm trying to unlock the chipset and advanced menus in the bios of my Jumper EZBook 3 PRO but without success.

I started by editing the "Setup" module from this

0x159BB         Suppress If {0A 82}
0x159BD             True {46 02}
0x159BF             Ref: Advanced, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0x2, FormId: 0x2712 {0F 0F 1E 00 02 00 02 00 00 00 FF FF 00 12 27}
0x159CE         End If {29 02}
0x159D0         Suppress If {0A 82}
0x159D2             True {46 02}
0x159D4             Ref: Chipset, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0x3, FormId: 0x2713 {0F 0F 1F 00 02 00 03 00 00 00 FF FF 00 13 27}
0x159E3         End If {29 02}

to this

0x159BB         Suppress If {0A 82}
0x159BD             False {47 02}
0x159BF             Ref: Advanced, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0x2, FormId: 0x2712 {0F 0F 1E 00 02 00 02 00 00 00 FF FF 00 12 27}
0x159CE         End If {29 02}
0x159D0         Suppress If {0A 82}
0x159D2             False {47 02}
0x159D4             Ref: Chipset, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0x3, FormId: 0x2713 {0F 0F 1F 00 02 00 03 00 00 00 FF FF 00 13 27}
0x159E3         End If {29 02}

and then I also added the "2 menu entries" in the "AMITSE" module from this

.. .. .. .. .. .. .. .. .. .. .. .. 4A 10 59 7B 
0D C0 58 41 87 FF F0 4D 63 96 A9 15 11 27 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 4A 10 59 7B 
0D C0 58 41 87 FF F0 4D 63 96 A9 15 14 27 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 4A 10 59 7B

0D C0 58 41 87 FF F0 4D 63 96 A9 15 16 27 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 .. .. .. ..

to this

.. .. .. .. .. .. .. .. .. .. .. .. 4A 10 59 7B 
0D C0 58 41 87 FF F0 4D 63 96 A9 15 11 27 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 4A 10 59 7B 
0D C0 58 41 87 FF F0 4D 63 96 A9 15 12 27 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 4A 10 59 7B 
0D C0 58 41 87 FF F0 4D 63 96 A9 15 13 27 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 4A 10 59 7B 
0D C0 58 41 87 FF F0 4D 63 96 A9 15 14 27 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 4A 10 59 7B 
0D C0 58 41 87 FF F0 4D 63 96 A9 15 15 27 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 4A 10 59 7B 
0D C0 58 41 87 FF F0 4D 63 96 A9 15 16 27 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 .. .. .. ..

but the menus are still locked.

At this link you will find two different BIOS rom:
- BIOS_V6_Date_12_05_2017_19_25_21_Ver_3BANS010_Jumper10x.P8.WP3132.NHNAUHL01.rom
This is the one that I'm currently working on and needs to be unlocked
- BIOS_V4_Date_08_07_2017_21_21_55_Ver_3BANS010_JUMPER10x.P8.WP313R.NHNAUHN02.rom
This one is an older hardware/software revision that wasn't factory locked.
I added this just for comparison.

Thanks to everyone who will try to help me

Hi,

 

If you have a jumper ezbook 3 pro V5 bios, get a bios mod with all options and full power limits in my google drive: https://drive.google.com/open?id=1TYLcH4usMEQF_vKRN0UTjzRD5QqTproP

 

Caution, this mod is only for V5 bios, downgrade or upgrade is a serious brick risk, compare a date of file rom with date of your bios.

 

If you have another bios version and need help, send me a rom and i help to unlock.

 

ps: Credits for hard work to unlock BIOS to Giovanni and @moetm in techtablets.com.

 

Regards.
